' HEMMER.

SPECIFICATION forming part of Letters Patent No. 331,021, dated November24, 1885.

Application filed March 6. 1885.

To all whom it may concern:

Be it known that I, AMos P. BARBER, .Tr., a citizen of the UnitedStates, residing at Rahway, in the county of Union and State of NewJersey, have invented certain new and useful Improvements in Hemmers;and I do declare the following to be a full,'elear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

Figure 1 represents the entire device, show- 1 ing in plan how thehemmer isplaced in position. Fig. 2 is an enlarged side view. Figs. 3and 4c are plan and side views of the regulatingplate for determiningwidth of hem. Figs. 5 and 6 are similar views of the hemmer.

This invention relates to improvements in hemmers. It has for its objectthe production of a hemmer in the use of which there is no clogging ofthe material.

In the annexed drawings, the letter A indicates the ordinary plate ofthe hemmer, by which the latter is secured to the machine bed-plate. Atone corner this plate A has formed on it two ears or verticalprojections, a a, between which is pivoted the tongue I; of

0 a forked plate, B, having a transverse rib, b, forming shoulders I) b.This plate B pro jects at right angles to the securingplate A. In thislatter plate, just under the tongue b, is made a slot, a, in which issecured a plate- 3 5 spring, a". On this spring the tongue I) bears whenthe hemmer is turned up, as indicated by dotted lines in Fig. 2.Extending underneath the plate B, and transversely thereof, is aslider-bar, G. This bar has downwardly 4o projecting lugs c c-one ateach endand also upwardly projecting lugs c, c. The latter come one oneach side of the forked plate B, and when the hemmer is down the formerlugs c 0 come one on each side of a tongue, D, projecting from the plateA, beneath and parallel with the plate B. Engaging the bar 0 is a SerialNo. 157,894. (No model.)

thumb-screw, E, which comes down between the forks of the plate B.

The hemmer proper, F, consists of a plate, f, having at one end theforksff, and loosely 5o hinged at the other end the folderf", having theusual shape, as shown. This hemmer is put in place on the plate B, beingaligned with the latter, and the forksff coming on opposite sides of thescrew E.

The regulatingplate G consists of a top plate, having the forks g g, andthe lower plate, hinged loosely to the plate the plate 9 being providedwith the piping-guide 9 For use the parts are put together as shown inFigs. 1 and 2, and placed in the usual place on the machine, the arrow,Fig. 2, indicating the position of the needle.

The material is placed in as indicated by the section a in Fig. 2. Herethe edge is turned into the folder f having been carried around theendofthe plate and the remainder hangs down, as usual.

It will be seen that the width of the hem is governed by the distancebetween the end 9 of the plate g and the folder f This distance can bevaried within certain limits to any degree by manipulating the screw Eand bar 0, and the two adjustable pieces, the hemmer and regulator, thelatter two being adjustable separately or together.

Should this device become clogged,the strain would cause one or more ofthe hinges to open, instantly relieving such strain and preventingbreaking. It will be seen that this advantage is obtained by my improvedhemmer when the regulating-plate is not used as well as with it.

By having the parts hinged several thicknesses can be sewed together, asthe parts 8 5 readily move, allowing more than one thickness to passthrough.

Having described my invention, what I claim 1s- 1. The plate A, incombination with the 0 hemmer F, hinged to such plate, and consisting ofplate f and folder f loosely hinged to ed under the plate f by a hinge,wherebythe Io hemmer has a free movement to prevent clogging, as setforth.

In testimony whereof I affix my signature in presence of two witnesses.
